More voters than ever get political news from their friends on social media platforms. Is this bad for democracy? Using context-neutral laboratory experiments, we ﬁnd that biased (mis)information shared on social networks aﬀects the quality of collective decisions relatively more than does segregation by political preferences on social media. Two features of subject behavior underlie this ﬁnding : 1) they share news signals selectively, revealing signals favorable to their candidates more often than unfavorable signals ; 2) they naıvely take signals at face value and account for neither the selection in the shared signals nor the diﬀerential informativeness of news signals across diﬀerent sources.
